To (1, It'll/mt if nuty concern..-

Be it known that l. (JHARLEs (J. Ba'r'rnv, a citizen of the United States of America, and a resident of Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Excavating-i\Iacl1ines, of which the following is a full, clear, and exact description.

This invention relates to improvements in excavating-machines especially available for digging dirt. sand, &c., from any place and delivering the same from its successivelytraveling shovels or buckets into a cart or other receptacle, and the machine is also well adapted for excavating for cellars and for digging trenches.

The invention consists in the combinations and arrangements of parts, all substantially as hereinafter fully described, and set forth in the claims.

The improved excavating-machine is illustrated in the accompanying drawings, in which- Figure l is substantially an elevation, some of the parts appearing in vertical section. Fig. 2 is a plan view of the machine. The sectionline on Fig. 2 indicates the plane on which the parts in section in Fig. 1 are drawn. Fig. 3 is a perspective view of one of the slmvel-lmckets. Fig. t a perspective view of an appliance carried in advance of the shovel-bucket for loosening the dirt or sand.

Similar characters of reference indicate corresponding parts in all of the views.

l he excavating-machine is portable, being mounted on a truck A, and on said truck is a platform U, centrallyswiveled, as indicated at (1, whereby such platform may have its position along the main platform of the truck, as shown in full lines in Fig. 2, or its position transversely thereof, as indicated by the dotted lines in said Fig. 2. At the end portion of the said platform C is an upright frame B, which serves as a support for various of the parts of the excavating apparatus.

The excavating apparatus comprises a duplicated sprocket-chain D, the same running around a sprocket-wheel I), mounted on a shaft (7, which is journaled in suitable bearings at an upper part of the said frame B. Said (No model.)

sprocket-wheel is driven from the motive power furnished by the engine or motor E on the truck-platform C, said engine having on its shaft a sprocket-wheel f, on which runs a sprocket-chain 7, which also runs around a sprocket-wheel g on the shaft (Z, on which the aforementioned sprocket-wheel .7) is affixed.

F and ("i' are duplicated booms pivotallyconnected at j and l at opposite sides of the platform C and carrying at their extremities duplicated guiding-sheaves l1. and 1, around which run the said sprocket-chains, said sprocket-chains carrying the shrwel-buckets J, suitably distanced one from another, and also the harro\\"ing appliances K.

The boom F in use is extended with downward inclination to insure that the chain-carried shovel-buckets will descend properly low to take earth or sand, while the boom G is upwardly inclined, so that the buckets guided around the end sheave thereof will be carried properly above the ground preparatory to dumping, and in addition to the booms F and G, carrying the duplicated sheaves, as mentioned, there is an intermediate duplicated bar or boom L, extended from one edge of the truck beneath the latter on a downward inclination and carrying sprocket-chain-guiding sheaves for holding the chains against undue slackening in their inclination in an up ward direction from contact with the depressed sheaves /4 and the higher sheaves 1' at opposite sides of the apparatus.

The boom F is made distensible, being composed of the slotted sections In and m, clamped together by the headed bolts m and clamping-nuts 111*, so that by temporarily loosening the nuts the members In and 111 may be slid endwise, one relatively to the other to lengthen or shorten the boom, so that the presentation ofthe shovel-buckets to the earth may be more or less distant from the center of the apparatus, as desired.

(he boom F has its position with the downward inclination more or less, as shown in Fig. 1, by gravity and as far as permitted by the suspending-tackle, consisting of windlass o, tackle-blocks n I), secured on the upright frame B and on an outer portion of the boom, respectively, and the rope 0, one end of which is connected to the ring-eye of the tively to the boom F in a different manner from that specifically shown, if desired, for either greater or less purchase.

The boom G, pivoted at 71' to the platform C opposite the place of pivotal connection 7' for the boom F, has pivotally connected to it at p the bar M, provided with the rack-teeth g, which engage with the pinion-wheel s in a train of gearing mounted on the upright framing B, said bar being borne upon at its upper edge by the roller T, which constrains the said bar M in its longitudinal movements to remain with its rack-teeth in engagement with the aforesaid pinion s. The train of gearing in which said pinion s is a part comprises the larger gear-wheel s on the same arbor with the pinion s, which meshes into a pinion s on the same arbor, with a larger gear-wheel s, which meshes into a pinion 8 on the arbor of which is a crank-shaft s.

The train of gearing aforementioned is operative with slight speed and great power upon the bar M to cause its endwise motion, and as a consequence the swinging of the boom G to a different inclination to adapt the excavator to have the shovel-buckets thereof work through a different course, changing of the inclination of. the boom G beingusually accompanied by a changing of the inclination of the boom F and in some cases by a distention of the latter boom. V Y

The shovel-buckets J may advantageously be of the form shown in Fig. 3,'comprising a,

scoop-shaped body, of which a is the edge of presentation to the earth, the opposite end being upwardly rounded, and this appliance has adjacent its end a the cross-tie member 20 provided with vertical ears a through which and the sides or cheeks a of the bucket securing-rivets are passed, and the said tie member has the longitudinal extensions if 21?. The tie members are riveted at u to the sprocket-chains, the said extensions a having a suitable length of bearing on thechains to prevent undue tilting of the shovel-buckets relatively to the chain, especially during the time of taking earth.

The rounded end portion of the shovelbucket has the reinforcing-pieces a a in the lines of the chains to prevent the latter from wearing the bucket near the rear corners thereof.

The harrowing device K, as shown in Fig. 4, comprises cross member n, of a length to extend across from one chain to the other, overlapping the chains, and the longitudinal tion.

members 41 '0 at the extremities of which and distanced from the cross member o such members o are riveted to thechains, as indicated at 0 and a plurality of tines o* are secured to and extend angularly from the cross member c.

The apparatus having the parts thereof adjusted for excavation and the truck being moved to the proper place at which the work is to be done, the running of the engine insures a continuous traveling movement of the sprocket-chains, causing the shovel-buckets to have circuits through a path such as clearly understood on reference to Fig. 1 of the drawings, the harrowing devices when used moving in advance of the shovel-buckets to loosen the ground, so that under some conditions the buckets will be enabled to freely take the earth.

The buckets becoming filled and carried upwardly around the guide-sheaves t' automatically discharge the earth therefrom adjacent the outside of the sheaves 2', the earth falling into a cart, if desired, or falling on the ground in a pile at a place remote from that of the excava- From time to time the boom F may be lowered to give increased depression in the .course of the shovel-buckets, which may be done by releasing the Windlass-pawl and unwinding the windlass to permit of the down swinging under its weight of the boom, and the path of the buckets may be further modified by imparting end wise movement to the bar M either inwardly or downwardly. From time .to time the truck may be moved so as to bring truck, and then moving the truck forwardly as the work progresses the trench or ditch of indefinite length may be dug.

On desiring to transport the excavating device the boom F may by the tackle be swung upwardly clear of the ground more or less,

as indicated by the dotted lines in Fig. l, and

the boom G may also be swung into an upright or approximately upright position for transportation.
